AC Solar Link Test
Used for diagnostic of the communications link between the Selectronic
Certified grid inverter(s) and the SP PRO in a managed AC coupled
installation. AC solar Link Test provides a count of any errors in the link.
When the system installation is complete and all inverters are powered
up and running, click “Reset Counters” then wait for 5 minutes. All
connected grid inverters should ideally read 0 showing there are no
issues with the communications link. A link error count of 4 or less per
minute is acceptable although it is recommended that the installation be
checked to ensure there are no issues such as the incorrect setting of the
RS485 termination resistor on either the SP PRO or grid inverters.
AC Safety Monitor
The AC INPUT SAFETY MONITOR detects the loss of the earth/neutral
link in the AC Source input to the SP PRO and instantly disconnects the
SP PRO from the AC Source whether it be a generator or the mains grid.
This important safety feature is included as secondary protection when
the AC Source is connected via a removable plug to the generator or
mains grid.
The primary protection for a plug in AC Source must be a
shrouded plug that prevents contact with the plug terminals
when removed from the socket.
This feature should only be disabled if the AC Source in hard wired to the
SP PRO and the wiring configuration will trip the AC Safety Monitor.
To disable this feature:
1. Set the New Monitor State to Disabled then click Set Monitor State.
Present Monitor state for all SP PRO inverters in the Powerchain system
will change to Disabled.
2. Set the EN - DISCONNECT switch within each of the SP PRO
inverters to Disable (DS). The State of Actual Switch field will change to
Disabled
Never disable this feature unless the AC Source is hard
wired to the SP PRO..
Setting For Poor Grid Quality
When the SP PRO is connected and synchronised to an external AC
Source (grid or generator), it is actively improving the quality of the
AC Source waveform. If the AC Source waveform is very distorted the
SP PRO may shutdown from a “Synchronous Overload Shutdown”.
Setting the Grid Quality to Poor or unmonitiored will reduce the
sensitivity to this distortion and allow the SP PRO to operate as normal.
